The least dense layer :plasma layer The puffy coat layer : leukocytes and platelets The dense layer : erythrocytes Platelets they help form clot Leukocytes fight infection Tgey are two types agranulocytes and granulocytes Granulocytes : neutrophils , eosinophils , basophils Neutrophils :phagocytosis Eosinophils : part of the allergic response they activate mast cell consider a big factor in the pathogenesis of asthma Basophils they secrete chemicals that respond to allergy antigen presenting cells Agranulocytes :mast cell , dendritic cells ,monocytes , T lymphocytes , B lymphocytes Dendritic cells : extremely important cells in the innate immune response , phagocytes and antigen presenting cells ( the cell that activate T lymphocytes ) Mast cells : the look like they contain granules They release histamine ( in the allergic response as well as in the inflammatory response which cause vasodilation and increse in vascular permeability ) Monocytes they circulate in the blood they phagocytes And when the migrate from the blood into tissues the become macrophage they have main functions they are phagocytes and antigen presenting cells ( they activate T lymphocytes ) T lymphocytes they are CD4 T cells , CD8 T cells , memory cells CD4 T cells promote the macrophage activity CD 8 T cells (cytotoxic) to kill infected cells tumors and abnormal cells B lymphocytes :plasma cells and memory B cells Plasma cells combat pathogens Memory B cells specific memory to particular antigen or agent

Make a video about Bloodclotting plzz!!

do you have any videos on the clotting cascade?

Thank u so much...but where is the clotting vid

great

I like your videos so much and really appreciate your effort. Can you please do a video on Coagulation cascade, PT, PTT, BT etc.

It's an AMAZING VIDEO! Is there a link where we can download the diagram??

Ohh thanks but I need video on blood products and what they do

I'm working to translate ur vedios to another language .. Thank you very much

how do you make these videos? love your presentation is there any special app that you use

Concerning monocytes, in my lessons, professor said that there is a lot of small granules called lysosomes, why did you put it in the agranolucytes categories?

sir l was read somewhere that basophill as a mass cell present in a blood and the granules of the basophill produce histamine and it also contain heparin ..........it is true or not

please do some disease process like rabies, measles, dengue etc. thank u! and i just want u to know that u r my key to pass my course HAHA

Thanks armando..what about clothing factors? U haven't talk at all about it..

First of all thank you so much for these videos, they're really useful. But I think you should erase the clotting factors from the title. Because I literally came for those lol

I came for clotting factors, didn't get clotting factors

❤️❤️❤️

can u please tell me where u bought ur "dryline clip liquid paper eraser"

How does blood travel around body is it by omosis or active transport or difussion?

Can you add stages of erythropoiesis

Sir 😅the video was perfect but I expected u will add clotting factors too

we need the widest view of your work, pls. and thanx anyway.

clotting factors ?

3:39 I'm confused. White Blood cell / containing pathogens / combating granules.

Think my brain just exploded 😥😥😥👀💣💣💣

I want those notesss wkwkwkkw

Please make a video with Indonesian language translate..🤗

" WBC: No Immature Cells Seen" What this means?

*platelet

Wasn't sure if you were aware of the spelling mistakes made throughout the video and in the title but all the "heme" words are incorrect. For example, haemotology should be hematology.

I suggest to allow us to translate ur videos by enabling this feature in ur youtube channel
